Late transit FA of a large active subfoveal CSCR leak. Focus is on peri-foveal vessels to give sense of height of large serous RD of macula. This patient presented with a BCVA of 20/200 and fluorescein and historic evidence of prior episodes of leakage. After discussion of known treatment options including observation, he was initially treated with rifampin and had partial resolution to 20/70 BCVA but this was short-lived with reaccumulation of the large serous detachment within 3 months. He then received sub-threshold micro-pulse laser photocoagulation with an 810 nm diode laser which resulted 1 month later in complete drying of the serous detachment and BCVA of 20/25.
